Application filed September 2, 1916. Serial No. 118,266. I

To all whom it may concern:

Be it known that I, J OHN S. BAKER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of Galifornia,'have invented certain new and useful Improvements in Cooking Apparatus; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification. A

This invention is a novel improvement in machines for treating packaged goods or so called can cooking machines of the general type shown in my Patent No.'1,182,832 of May 9, 1916; and the object of this invention is to provide a machine capable of great flexibility of Operation and. in which the feed can be readily adjusted or shifted so as to feed cans into anydesired run of the canway or at any one of a number of points in the canway; and also if desired to provide this machine with a discharge which can be adjusted to discharge cansfrom any desired run of the canway. In this way a great variety of lengths of cooks or treatment of the packages or cans in the machine can be obtained; and if desired the feeding and delivery devices can be provided with or construction of rotary valves so that the machine can be practically used as 'a high temperature machine with speed.

An essentially novel feature of the machine is having the feeding devices adjustable transversely of the series of runs in the canway so that the same feeding device can be used to deliver cans to different runs of the canway, and also if desired eachend of the machine may be equipped with adjustable feeding and delivery devices so that a plurality of series of cans can be simulta-;

neouslypassed through the machine and each serles of packages or cans glven a different length of treatment or cook, according to tion enable othersskilled in the art. to adopt and use the same; but I do not consider the invention restricted to the particular form arts shown as when once understood the a aptability of the 111V0n-1 tion to different varieties and structures of the machine can be readily appreciated by those skilled inv the art. The essential feature of construction and combinations of parts for which protection is desired are summarized in the claims following the description.

In said drawings:

Fig. 2 is an enlarged detail elevation of one endof such machine.

Fig- 3 is a longitudinal sectional elevation of one end ofsuch machine.

Fig. 4 is an enlarged detail end elevation thereof. a

Fig. 5 is a longitudinal sectional View of one end of such machine showing the rotary valves used in connection with the feeding and delivery slides. v A

Fig. 6 is an enlarged detail end view of Fig. 5.

Figs. 7 and 8 aredetail sectional views showing means for controlling the entry of cans from the canway into the discharge valve.

Referring to said drawings, 1 designates a tank orcooking chamber which may be of any suitable construction, substantially such for example as described in my aforesaid patent. Within this tank is a preferably endless spiral canway 1 around which the cans may be traversed in a spiral path; this canway may be constructed substantially as described in my said patent or in my Patent No. 1,181,057 of April 25,

1916, andppeeds no detailed description herein. v i I The cans may bepropelled around this canway along the spiral canway by means i of pusher bars 2 connected to endless chains- 2 operated as described in my aforesaid patents. On each end of the tank may be formed a casting 3 which may be provided with 'a lower Opening 3 and upperopening 3*;this casting may be curved so that its innerface will practically form part of the outer wall of the canway to guide cans around the bend of the canway as in my said Patent N 1,182,832. The opening 3 is closed by a slide 4: and the opening 3 by a slide These slides 4 and 5am.

respectively guided in grooves formed in the casting 3 attheupper and lower edges of the openings therein as shown, see Fig. 2; and intermediate the openings may be formed a guard to the casting 3 and pro jecting transfer bar or bracket 3 which may be provided with racks 3 and 3 on its upper and lower sides respectively.

The slide 5 is provided with a feed opening 4 'and to this slide is bolted a feed chute 6'which is adapted to receive the cans or packages to be .fed into the machine from any suitable feeding devices, not shown, which maybe such as are used in canne'ries.

The delivery slide 4 is provided with a discharge opening 5 to which may be "attached a discharge chute 7 to direct cans from the opening in any desired manner. The slide 5 with the opening 4 is adjustable transversely of the tank or canwaypreferably by means of a hand wheel 4 1 carrying a pinion 4 which meshes with rack 3, said hand wheel' and pinion being rotatably. mounted on a stud 4 attached to the slide 5 so that when the hand wheel 4? is turned the slide 5 can be adjusted transversely of the machine.

', are preferably of such diameter that for the operator can 1 a complete rotation either pinion will move the related slide the Width" of one run of: the canway and as these slides are adjustable transversely of the tank and canway feed so as to deliver cans into any. desired run of the oanway,.or he can adjustthe discharge so as to let cans escape-from any desired run'o f the canway; thereis only one discharge-opening and one feed opening on each slide; while more might be used I do not consider this desirable. ,However' to enable a plurality of cans to be simultaneously fed to and delivered from this machine in series the feeding and delivery slides 4 and 5 can beduplicated ateach end of the machine as indicated in Fig. 1 so that cans can be fed and discharged through both ends of the machine if it is desired.

In the'example shown in Figs. 1, 3 and 5 the feed chute 6 projects sufficiently into the machine beyond the inner edge of the cast ing. 3 as indicated at 6 to deliver the cans properly into the run of the canway; and preferably a filler or guard 6 "is provided beneath the lower inner edge of the chute so that incase one of the pusher bars 2 should be bent and project outwardly suiticiently to otherwise engage the pro ecting inner end of the feed chute it would engage this deflector or guard 6 and be directed inlery readily adjust the.

wardly thereby past the inner end of the chute without injury and without breaking the pusher bar or the chute.

'llhedischarge hood 7 is indicated in detail in Fig. 3 and is adapted to deliver cans into a trough S- from whence they may be removed by a chain 8 which would be operated'by suitable means, forming no part of the present invention, so as to carry off the cans. If desired the hood 7 might be provided with a vent opening 7 in its upper side which can be connected with pipe 7 to carry ofi vapors which might enter the hood.

In some cases it might be desired to use valve casing 6 could be attached to the chute 6, see Figs. 5 and 6, and within this be mounteda rotary valve 9 provided with pockets 9 and the cans can be fed into these pockets from any suitable feeder, and also the valve may be rotated by any suitable means and'in a manner so as to take the cans successively from the inlet, at 6' and deliver them to the chute 6. Similarly the dischar e chute 7 may be provided with a casing in which is a rotary valve 10 having pockets 10 adapted to receive cans successively from the chute 7 and discharge them at the outlet 7' into any suitable receiver. The valves 9 and 10 are to be simultaneously operated and any suitable means may be employed for operating these valves, but they must be operated-in-unison with each other and also in uniformity with the pusher bars 2 as the same travel past the feed. chute 6 and the discharge chute 7. With this construction however it will be observed that considerable pressure might be employed in the cooking chamber or tank so as to subject the goods therein to unusually high heat or greater heat than would be possible with the feed and. discharge passages shown in Fig. 1.

By this construction very great flexibility of the machine is obtained and great simplicity afforded,-for it will be observed that in the machine shown in the drawings the cans or packages can be fed for example at the right hand end of the machine and be caused to traverse any desired number from the canway at any desired point. If

it is desired that the cans or packages shall traverse the entire lengths of the spirals of the canway the'slide 5 is adjusted toward the left hand side of the machine for posithe slide 5' is adjusted toward the right hand side of the machine orthe slide t'may be adjusted toward the left hand side of the machine in which case the cans or packages maybe passed'through the left a hand portionor the right hand ortion of the machine as desired in accor ance with the temperature of the chamber at therespective points. "If,hoWever, it is desirable that-the cans or packages should traverse any of the intermediate runs of the canway the slides '5 and l'may be simultaneously adjusted toward each other in a manner to' cause the cans to traverse more or less. of the runs (3f the canways substantially at the longitudinal center of the machine.

Should it be desired to treat series of pluralities of eans or packages the machine may be provided at its opposite or rear end with a duplication of the parts just describedand as indicated in Fig. 1, whereby the feed and delivery slides 5 and twill be adjusted in thet na-nner' above set forth for varying the length of treatment of the cans .at the front end. of the machine, andif desired the feed chute 6 and .the delivery chute or hood 7 at the rear end of the machine mayalso be provided respectively with the rotary valves 9 and 10 as indicated at the machine in Fig; 5 of, the

front end of the drawings.

When the rotary valves are used as indicated in Figs. 5 to 8,.it is desirable to' control the entry of cans from the canway into the discharge. valve so as toi'prevent 4 cans from entering the pocket of the valve out of time and to insure that the cans shall notbe caught between the edge of the valve pocket and the valve casing, as might sometimes'happen and result in crushing or 111-.

juring the cans. Therotary valve'lO does not necessarily operate in exact unison with the detent' ll depends into the pathway of the cans G and will arrest such can before it can contact with therotary valve 10-. On the shaft 11 is a crank 11 which is connected. by link 11 to one end of a lever 11, pivoted at 11 on the side of the valve casing.

As shown in Figs. 7

This lever is preferably provided with an antifriction roller 11 which is adapted to engage a cam 11 with the shaft 10 on the valve 10; The lever l1 may be normally retracted, or moved to hold the roller l1 in Theoperation issuch that the detentll is held in the position indicated in Fig; '8 until the pocket 10 in the valve 10 practi' cally registers with the chute 7 as indicated and the can rolls down into the pocket. Then the lever 11 under the action of spring 11, is permitted by the cam 11 to assume -contactwith the cam 11, by means of a spring; 11.

in Fig. 7, whereupon the detent is. raised r.

the position shown in Fig. 8, so that such detent will arrest'the incoming can in the position indicated in Fig. 8 until the next pocket has registered with the chute 7, whereupon the dete-nt-is raised to the p0 sition indicated in dotted lines in Fig. 7

and the can-permitted to roll into the pocket and the detent returns to the position in- .dicated in Fig. 8'to arrest the next can until a-pocket has properly registered with the chute. The valve casing 10 is provided with an outlet 10? through which the cans are successively discharged from the pockets. If desired a'similarcan detent might be.

employed in connection with the rotary inlet valve. t
